Firstly, you can change the price of an item in two ways.

1. Inventory Management - Definitions - Stock Definitions section: You can manually change the purchase and sale prices of an item in the "Prices" section. However, this operation only applies to the "Margharita Pizza" stock.

2. Inventory Management - Reports - Definitions List - Price Change / Price List - Operations - Price Update section: You can update prices by groups or collectively.

For example: Let's update the prices of the items with the group "Margharita Pizza" collectively.

You can increase or decrease the prices of items with the group "PIZZAS" in the fields shown in the image below collectively.

At the same time, you can also perform operations such as changing purchase prices, converting prices, rounding, creating sales prices, and changing turnover prices.

You can also manually change the prices of your groups or all your stocks manually from the Inventory Management - Reports - Definitions List - Price Change / Price List - Operations - Manual Price Change section.

When you click on Operations - Manual Price Change section, you will encounter the "Price Update" screen. This section includes "Account" and "Price No" fields.

It is important to pay attention to these fields. You must write in the price number section which sales price of the stock you want to change because the opened screen allows you to make changes manually based on the sales price number you entered in the "Price No" section.

For example: Let's manually change the "Sale Price 1" of the items with the group "PIZZAS".

NOTE: The "New Price" section in the image below turns blue after you manually enter each new price.
